中文摘要：

选取位于北疆东、西和西北部的3个典型蝗区，即哈密、伊犁和塔城为研究区域，采用合成分析和距平分析方法，研究温度和降水对3个不同地区蝗虫发生的影响。结果表明：（1）蝗灾发生严重年份与一般年份的月均温度和月降水有显著差异。（2）蝗虫严重发生的年份，产卵期间（上一年7～8月）的平均气温偏高。（3）塔城和哈密地区，冬季气温较高，孵化期（5～6月）气温偏高、降水偏少有利于蝗灾的发生，而伊犁地区蝗虫大发生年份与常年比较，冬季和孵化期（5月）的气温偏低。

英文摘要：

Effects of temperature and rainfall on locust infestation in the north of Tianshan Mountain in Xinjiang were examined by methods of composition and anomaly analysis during 1990-2001. Results indicated that temperature and rainfall had significant differences between years of infestation and no-infestation, and higher temperature during oviposition was helpful to locust occurrence. Also, higher temperature in winter and higher temperature with less rainfall from May to June contributed to grasshopper outbreaks in Tacheng and Hami areas, while temperature is lower in infestation years during hatch period and in winter in Yili area.
